Maintenance and troubleshooting the connected dimmer, Zigbee®

Reset mode

A reset of the connected dimmer results in:

Removal of all data. You will need to link a new address to the device via the Niko Home Control programming software or the Niko Home app
A disconnect of the dimmer from your Niko Home Control installation
Switching of the built-in contact (default status)

ZIGBEE® NETWORK RESET

As of the Niko Home Control 2.16 release, a Zigbee® network reset can be initiated by the programming software via the diagnostics page: Diagnostics Page > Network settings > Reset Zigbee network.

Only active Zigbee® devices will receive the reset messages and leave the network with its internal configuration data cleared. These devices can be reused in another Zigbee® network without the need for being reset manually.

Active devices are for example 230 V powered devices that always ‘listen’ to the Zigbee® network. Zigbee^® devices are only active when they are being used and 90 seconds thereafter.

The Zigbee^® controls will not receive the system reset message if they are not active. It is recommended to reset the Zigbee^® devices manually (see Factory Reset) before using them in another Zigbee® network.

The Zigbee® network reset function clears the entire Zigbee^® network, including the network channel and network ID of active Zigbee® devices.

Upgrading the connected dimmer

When an upgrade is available, you are informed in the latest version of the Niko Home Control programming software or Niko Home app. An OTA upgrade is not indicated via the feedback LEDs. Only when the connection to the smart hub or wireless bridge is interrupted during the OTA request, a red LED will blink briefly.

All Zigbee^® devices are automatically upgraded one by one. The upgrade of Zigbee^®devices starts within max. 6 hours after the smart hub or connected controller has been upgraded.

When an upgrade fails, you are notified in the Niko Home Control programming software or Niko Home app. The Zigbee^® device remains operational with the previously installed software version.

Replacing the connected dimmer

Switch off the mains

Remove the faulty connected dimmer and install a new one. See Installation.
Open the Niko Home app
Remove/delete the faulty Zigbee^® device via the hamburger menu (≡) > Settings > Devices

As of the Niko Home Control 2.16 release, it is possible to remove an individual Zigbee® device via the diagnostics page of the Niko Home Control programming software (Diagnostics page > Zigbee® devices > Remove).
Add the new Zigbee^® device via the same menu
Add the new Zigbee^®device in the desired actions or routines
Pair the new connected dimmer to the Niko Home Control installation (see Connected use of the connected dimmer, Zigbee^® > Onboarding):

- Via the Niko Home Control programming software
- Via the Niko Home app

The address of the defective connected dimmer is automatically overridden when addressing the new one.

FAQ

What happens to the connected dimmer when I replace or reset my wireless smart hub?

The wireless smart hub is the master of the Niko Home Control installation. Therefore, it will need to re-address the Zigbee^® devices in case of a reset or replacement.

It is sometimes possible to retrieve network settings from the defective smart hub. Contact Niko customer services to verify if the previous settings can be restored.

Proceed as follows:

Using the Niko Home Control programming software: address all Zigbee^® devices one by one in the Addressing tab. (See Connected use of the connected dimmer, Zigbee^® > Onboarding.)
Using the Niko Home app: link all connected dimmers one by one via the hamburger menu (≡) > Settings > Devices > Connected dimmers. (See Connected use of the connected dimmer, Zigbee^® > Onboarding.)
To connect a new wireless smart hub, add each Zigbee^® device to the desired action or routine via the same menu.

What happens to the connected dimmer when I replace or reset my wireless bridge?

The connected dimmer cannot find the network it was previously added to. The red LED will blink, and it will fall back to its default behaviour (switching the local relay).

Perform a factory reset to (re)link the connected dimmer to the wireless bridge. See Reset mode.

Troubleshooting

Problem	Cause	Action
I want to use the connected dimmer but I don’t yet have a smart hub or wireless bridge to connect it with	All 230 V connected devices for Niko Home Control can be used in stand-alone mode until they are connected to a smart hub or wireless bridge. In this mode, they only switch or dim their own contacts. If extension switches are wired to the connected dimmer then they can also be used in stand-alone mode	Connect the dimmer contact to the lighting circuit that you want to control in stand-alone mode
My smart hub or wireless bridge doesn’t work anymore	Consult the manuals of the wireless smart hub (552-00001) or the wireless bridge (550-00640) for more information on the possible cause	If the power of the smart hub or wireless bridge switches off, all 230 V connected devices will continue to operate in stand-alone mode. They will only switch or dim their own contact
The connected dimmer cannot be found in the Niko Home app or programming software, or it cannot be paired into the network	The power supply is off	Switch on the power supply
	The connected dimmer and the smart hub or wireless bridge are located too close	Make sure there is a distance of at least 2 meters between the Zigbee^®device and the smart hub or wireless bridge for Niko Home Control. The same minimum distance must be respected between the Wi-Fi router and the smart hub or wireless bridge
	The connected dimmer and the smart hub, wireless bridge or another connected device are separated too far from each other	Make sure there is a distance of maximum 10 meters between the device and the smart hub, wireless bridge or a subsequent 230 V connected Zigbee^® device. To increase the range, you can for example add an additional 230 V powered Zigbee^®device to the network
	There is no connection between the Niko Home app or laptop/pc and the smart hub or wireless bridge	Check the connection to the smart hub or wireless bridge. Consult the respective product manuals to resolve this issue
The load does not switch on	The miniature circuit breaker (MCB) of the lighting circuit is disabled or there is a short circuit	Check whether the lamp complies with the load specifications specified in the manual
	The switch is used during a transition period when the RF connection to the smart hub or connected bridge is lost	After the transition period, the feedback LED should blink red and the device can be used in stand-alone mode
	The minimum dimming level is set too low	Increase the minimum dimming level or a profile with boost function (LED 3, LED 7 or LED 8).
	The input voltage is not present	Check the input voltage, connection terminals and wires, light source and dimmer and replace it if necessary
	The lamp is defective
	The dimmer is defective
The dimmer switches off suddenly	The protection against thermal overload (temperature is too high) or short circuit has been activated	Check if the lamp is dimmable. This is shown on the packaging by the following symbol:
		Check if the load is too high. Remember to consider the reactive power of ferromagnetic transformers. LED lamps that generate peak currents can also cause the dimmer to switch off even if the maximum dimming power has not been reached
		The temperature in the flush-mounting box should not exceed 35°C. Lower the load that is connected to the dimmer
		Check whether mixed loads have been used. Make sure that there is only one type of lamp load in the lighting circuit
	The dimming profile is incorrect	For LED lamps: Test all lamp profiles one by one and choose the profile that works best. Dimmable LED lamps that require a boost function (which do not start up at the minimum dimming level) can be controlled with lamp profiles LED 3, LED 7, or LED 8. For incandescent lamps, choose lamp profile LED 1. For halogen lamps with a ferromagnetic transformer, choose lamp profile LED For LED lamps supplied with a ferromagnetic transformer, choose lamp profile LED 3. For halogen lamps with an electronic transformer, choose lamp profile LED 5
The lamp flickers	The lamp is not dimmable	Check if the lamp is dimmable. This is shown on the packaging by the following symbol:
	The minimal dimming level is set too low	Increase the minimum dimming level or use a profile with boost function (LED 3, LED 7 or LED 8)
	The 2-wire dimmer does not get enough current from the lamp	Fit one or more LED compensators (310-05001) over the lamp, between the switching wire and the neutral wire
	The dimming profile is incorrect	Choose another profile and adjust the minimum dimming level
	There is a Power Line Communications (PLC) interference	Refer to the FAQ on dimming at www.niko.eu/faq
	The lamp has a capacitive electrical profile and generates high current peaks	Reduce the number of lamps in the lighting circuit or replace the lamps if the other actions listed above did not resolve the lamp flicker
	The dimmer is defective	Replace the dimmer
The lamp does not switch off completely and displays an afterglow	Leakage currents can cause low power lamps to remain illuminated (afterglow) when the electrical circuit is disconnected. Long cabling can build up leakage currents due to capacitive effects	Fit another lamp with a higher electrical load or fit a LED compensator (310-05001) over the lamp, between the switching wire and the neutral wire
The lamp is humming/ makes an audible noise	The lamp is of bad quality	Select dimming profile LED 4, LED 5 or LED 7. When the lamp flickers, it is an indication of a capacitive electrical behaviour. In that case, we recommend fitting a different lamp
When I use the MIN DIM LEVEL button, I cannot switch the lamp back on	The minimum dimming level is below the lamp’s power-on level	Select a dimming profile with boost function: LED 3, LED 7 or LED 8
